A 20HP crusher (typically 15kW) is a robust industrial machine for size reduction, mainly for plastic recycling, effectively shredding hard/soft plastics, bottles, barrels, films into reusable flakes/pellets, featuring alloy blades, easy maintenance, overload protection, and often a cooling system, offering high output (500-1000kg/hr) for cost-effective material recovery in injection molding and extrusion.
